Programme

New Zealand’s aquaculture industry is growing in response to globally increasing demand but is constrained by limited access to sheltered inshore farm space. The new frontier is open ocean aquaculture, where large tracts of consented space are available but farming is challenging in exposed and dynamic waters.

New engineering concepts and farming approaches are needed to maximise the sustainable production potential of the challenging open ocean environment and give industry confidence to invest.

Cawthron Institute is leading the country in advancing open ocean aquaculture technology through the development of new tools and methods to cost-effectively farm shellfish and finfish.

With technology opportunities progressing at pace, Cawthron’s Open Ocean Symposium is a unique opportunity to bring together industry and global research leaders to discuss New Zealand’s open ocean aquaculture potential.
